mpi-sys-0.2.0

(cargo-release) mpi-sys version 0.2.0

mpi-0.6.0

2022-08-05

MSRV: 1.54.0

Notes

In order to use the user-operations optional feature (enabled by default), you may want to check
that you are using at least libffi-sys version 1.1.0. This can be done by running cargo update, but for most users this will likely be unnecessary.

New Features

• [PR 122] Multiple request completion via MPI_Waitsome and friends.
• [PR 113] Make Communicator and Group traits object-safe
• [PR 110] Implement Buffer and BufferMut for Vec,
  allowing cleaner syntax

• [PR 52] Safely send and receive structs with arbitrary
  data layout, including padding, using #[derive(Equivalence)].
• [PR 88] Support for MPI_Waitany using mpi::wait_any.
• [PR 46]
  MS-MPI on Windows
  is now supported.
• [PR 58] Support for "cartesian" communicators using
  CartestianCommunicator
• [PR 51] Support MPI_Pack and MPI_Unpack using
  Communicator::pack, Communicator::pack_into, and Communicator::unpack_into.
• [PR 49] Build compound datatypes without committing
  intermediate types using UncommittedUserDatatype.
• [PR 53] Construct a UserCommunicator from an
  MPI_Comm with UserCommunicator::from_raw.
• [PR 90] Support MPI_Comm_split_type using
  Communicator::split_shared, which splits communicators into subcommunicators that are capable
  of creating shared memory regions.
• [PR 27] Support for MPI_Comm_get_name and
  MPI_Comm_set_name using Communicator::set_name and Communicator::get_name.

Changed APIs

• [PR 48] UserDatatype::structured no longer takes a
  count argument.

Fixed Bugs

• [PR 77] Failure to complete scoped requests now results
  in immediate process termination, rather than a panic.
• [PR 53] Portability improved with newer libffi and
  bindgen
